Sorry , this is my config
accounts_server_host = ldap://server1.home.com:389,
ldap://server2.home.com:389
accounts_search_base = ou=home,dc=com
accounts_query_filter =
(&(objectClass=user)(!(objectClass=computer))(mail=%s))
accounts_result_filter = %d/%u/
accounts_result_attribute = mail
accounts_bind = yes
accounts_bind_dn = cn=conector,cn=Users,dc=home,dc=com
accounts_bind_pw = ***********
I test but don't work

You could elaborate on this description of the problem. The level of
detail could be greater.
Multiple servers in a single LDAP table are not a mechanism to extend
searches over multiple LDAP databases when records are not found in the
first database. Rather the second server is only used when connections
to the first server cannot be established.
If you want to stack LDAP databases, use multiple LDAP tables in
alias_maps
virtual_alias_maps
generic_maps
...
With multiple tables, each table is consulted in turn until one matches.

For more details of my problem, when the server is not responding
ldap1 by technical problems, Postfix rejects all email me saying that
the mailbox does not exist, when the user exists.
Recipient address rejected: User unknown in virtual mailbox table
So nagios began to warn that the SMTP service did not respond at
intervals, making access to the server slow.
alias_maps = hash: /etc/aliases
virtual_alias_maps = hash: /etc /postfix/virtual_alias
virtual_mailbox_maps = ldap: accounts
I have many tables as you can see, but are not equal between them,
each serves a purpose. then do you recommend?
Greetings
Michel
